This standard applies to task chairs for office work with Visual Display Terminals (VDT) by providing dimensional and adjustment requirements. This standard also defines test methods for measuring chairs and assessing their performance.

This standard also provides for dimensional and adjustment requirements that respect generally acceptable ergonomic guidelines such as those of ISO 9241-5, using NATICK/TR-89/044 as the source of anthropometric data.

The dimensional and adjustment requirements aim to address the estimated needs of the 5th to 95th percentile of the office working adult population, based on such anthropometric data.

Quantities and dimensions used in this standard are given in metric units with imperial equivalents following in brackets where appropriate. The metric units shall be regarded as official in the event of dispute.

The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
